ABSTRACT:
A prosthesis which is to be incorporated with the aid of cement has a support plate (24), which projects beyond a shaft (32) on all sides. Constructed in the shaft is an axial supply duct (36) for cement and a suction aperture (56) is provided in a projecting lateral section (28) of the support plate (24). The distal boundary surface of the support plate (24) supports a plastically deformable sealing frame (52). In this manner, the space between the corticalis internal surface and the shaft external surface is closed in a sealing-tight manner and can be evacuated by a suction pump (64). As a result, the intermediate space between the corticalis and the shaft can be filled with cement in an inclusion-free manner.
